Torben Lonne (Diving Instructor): Well +Sadegh Balef as it's an article on yahoo - the picture is from Flickr, I'm sure you'll find plenty of phoos there to your liking. Otherwise look around in the community, there's plenty of great pictures here..

You’ve seen best-diving-site lists before. This one is a little different because I weighed more than just awesome diving (any of the world’s top destinations can offer that). I considered the variety of dive conditions, social atmosphere, facilities, and infrastructure available locally as well as the variety of activities in each locale.

Torben Lonne (Diving Instructor): It's a very good point +Alexander Ufimtsev - and properly why it's most common in the tech world. Thanks +Alex Bean

Adam Zysk: There have only been a handful of times in over 20 years of diving (in many differing conditions) when I would have liked to have had one. And I agree with Alexander, it would have only been used for a short time. I can see it end up being one more thing that gets lost along the way.

Torben Lonne (Diving Instructor): Agree +Adam Zysk​ lost or just take up space among all the other gear.
